Well, if you fall into the group of “new betta owners” then you might be thinking of whether bettas need darkness or not. However, most betta owners have mixed opinion regarding this topic. Bettas sleeping patterns also makes the topic more complicated. 

Bettas prefer darkness while they sleep. Because the darkness will help them to have proper sleep. Therefore, it is recommended by the experts that you should provide darkness to your betta for at least 10 to 14 hours every day.

Therefore, in this article, I am going to cover details about whether bettas need darkness to sleep or not.

How Long Must It Be Completely Dark For Betta Fish?

The usual darkness requirement for betta fish is 13 to 14 hours per day. This means that just 8 to 10 hours should be maintained each day with the tank or aquarium light on. Owners should determine the precise amount of illumination their bettas require. 

Your betta might not get an adequate amount of sleep if the tank light is left on for an extended period of time. Eventually, your fish will become so anxious that they won’t eat. Additionally, the stress may contribute to the development of illnesses that reduce their longevity.

On the other side, giving your betta too much darkness for too long might be harmful. To minimize stress and maintain their health, these fish require a regulated cycle of light and darkness.

Why Betta Needs Darkness To Sleep?

Betta fish need periods of darkness to sleep adequately, much like the majority of fish. A fish will become more motionless and less energetic when it is “sleeping.”

Betta fish are no exception to this rule, however since they have a tendency to be more lively at night than other fish, there is sometimes misunderstanding regarding the lights-off requirements for betta fish. They frequently swim around at night in search of food, and occasionally they may even appear from hiding spots, which is one of the reasons for this.

The amount of darkness a betta fish needs each day should be at least 10 to 14 hours. The maximum amount of time your aquarium light should be on every day is ranging from 8 to 10 hours. Don’t forget to gradually ease the fish into and out of darkness by using room light or natural light instead of suddenly switching from darkness to light. 

Let’s get some information about betta fish’s nighttime vision so that we can determine if they require darkness or not. This will enable you to comprehend the information more precisely.

Their Vision In The Night

Normally, in the dark, betta fish have very poor eyesight.  Due to their sluggish iris, betta fish have relatively poor eyesight and can’t react rapidly to changes in brightness. Bettas are hunters that primarily rely on their eyesight, making them more reliant on it than any other sensation.

Betta has extraordinary eyes. Due to its monocular, each eye perceives a different image. What we would like to do is explain that. Imagine that each of the human eyes can only see one item at a time. It is known as binocular vision. 

This implies that we can only maintain our sight in one direction at once. This is an unpleasant experience for animals with binocular vision. There are a number of adaptable pressure receptors all across the length of betta fish. 

There is a faint line that runs from the head to the tail and allows for smooth bends. In comparison to the skin tone, these lines are often a little darker. These lines are a collection of tiny boxes that include pressure-sensitive and movement-sensitive cells that can detect minute changes in water pressure.

Every living thing needs to sleep and they prefer darkness to sleep. Whether betta favors light or dark environments is unknown but surely they prefer dark environments for sleeping. They most certainly have a choice that falls somewhere in the middle, just like humans.

Betta Fish Sleeping Patterns

Similar to all other species, betta fish require sleep to survive. Betta fish sleeps in a variety of habitats and environments. Some of them bury themselves in the tank’s pebbles, while others hide within an aquatic decoration, yet others cram themselves between the filter and the tank, and still more float at the very end.

Betta fish are considered predators which is why they are much more active at night time. But bettas are known for their midday “catnaps,” which can last only a few minutes. Therefore you should make sure that there is darkness when the betta takes those catnaps in the daytime.

How Much Lighting Does A Betta Fish Prefer?

Generally speaking, artificial lighting is best for betta fish raised in tanks. In comparison to natural sunshine, this illumination allows owners to have more control over the day and night cycles. It’s simple to choose artificial lighting for your betta fish aquarium. Any LED bulb, as far as it isn’t too bright, should work.

The light from these inexpensive bulbs has no impact on the temperature of the water. Likewise, fluorescent illumination is a wonderful option for betta tanks. This illumination aids in promoting plant growth. 

Fluorescent lighting is the best option if your tank has a sizable amount of actual plant. Avoid using incandescent lights since they might heat up the water in the tank and disturb the habitat in which your fish live.

Betta fish require temperatures of 79 to 81 degrees Fahrenheit to flourish. They have a brief tolerance for temperatures as high as 84°F. If they are kept at such a heated temperature for an extended period of time, they might die.

Since blacklights make betta fish look more vibrant, some owners employ them in their aquariums. Blacklights should not be the main source of illumination for betta aquariums, though. Natural lightings, such as that found in rice fields and shallow standing waters, is necessary for these fish. 

Therefore, if you do add a blacklight to your tank, you should only occasionally utilize it. Avoid using any additional surprise lighting as it can distract the fish and interfere with their ability to sleep.

You may install timer-controlled lights in your tank to guarantee that your betta fish gets enough “dark” time. These timers may be configured to switch on at dawn and switch off at nightfall. This is an excellent alternative for betta fish owners who find it challenging to turn their aquarium lighting on and off each day.

Do Bettas Prefer Blue Light At Night?

White or blue LED lights are often found to be suitable for the demands of betta owners. These hues serve to highlight the vivid colors of your betta fish while also offering decent clarity without overstimulating. 

It is recommended by the experts to use dim lighting as the betta prefers lights that are less brighter. You can use a softer hue light that will offer soothing lighting without becoming overpowering. 

Wrapping Up

The majority of betta owners are perplexed or believe the sleeping betta to be dead. Therefore, if you are a new betta owner you will need to have a proper idea about this topic. That is why I recommend you to read out my next article. Is My Betta Fish Dead Or Sleeping?
